Thank you for viewing. Regarding discounts, I may offer a price reduction for combined purchases if items can be shipped together, to cover the difference in shipping costs. However, I generally decline other price negotiations. Also, I've included a brief product description (taken from the sales site) below. Please note that for unused items, I often haven't personally used them, so I may not be able to answer all your questions. Thank you for your understanding. -----Product Description Below----- Product Condition: Unused Tatybo Gaming Headset Gaming Headphones ps5 ps4 Switch Headset bluetooth Headphones 【USB-C & USB Wireless Receiver/Bluetooth/3.5mm Wired 3-Way Connection】ENC Noise Canceling 30 Hours Continuous Use PC Smartphone 50MM Driver 7.1ch Low Latency Detachable Microphone Lightweight (Black) ● Tatybo's self-developed 4-way connection: ① 2.4GHz TYPE-C wireless receiver connection, ② 2.4GHz USB-A wireless receiver connection, ③ bluetooth 5.3 connection, ④ 3.5MM wired connection. ● The 50mm diameter driver unit achieves a high level of both high-definition detail depiction and sharp, deep bass reproduction, allowing you to enjoy high sound quality unique to gaming. ● The microphone part of the headphones is detachable, so when playing games that don't involve voice chat, or when using the headphones for purposes other than gaming, you can use them as high-quality USB headsets with the microphone removed, achieving high versatility. ● Full charge "2.5 hours" The continuous operating time of the battery is up to 40 hours when connected via 2.4GHz and the LED is off. ● Package contents: Gaming headset body, detachable noise-canceling microphone, USB-A & TYPE-C transmitter, 3.5MM audio cable, USB-C charging cable, instruction manual.
